The Earl was marking an incredible milestone, as he noted the 500th-year anniversary of the passing of his late ancestor, Sir John Spencer, who served as a politician and was knighted during his lifetime. Charles shared an intimate glimpse inside his private tomb, where a stone figure with its hands together in a prayer gesture was lying in rest.

"The tomb of my ancestor Sir John Spencer - who died precisely 500 years ago today, on 14 April 1522," he wrote.
"He bought the farmland around Althorp, and then built @althorphouse in 1508. Businessman, sheep farmer, sheriff, and politician, he was knighted by Henry VIII in 1519."
His fans were touched by the post, as one sweetly penned: "Where is this tomb located? Its detail is impressive. I'd love to see his face. He would have missed the reformation times. He would be proud to know his home is still in great hands."

Earlier this year, Charles shared a stunning black-and-white photo of the 550-acre property from the 1800s and revealed an old wing of the building that was no longer there.

"In the 19th century Althorp briefly had a billiard room / extra library - the additional wing is visible towards the left of this photograph," he explained in his caption.
And fans were quick to ponder why the billiard room and extra library had been removed.

One asked: "Why was the wing removed? Was it purely in the interests of symmetry, or was there some other reason for the brevity of its existence?"
A second questioned: "What happened to it?" and a third queried: "What happened to the additional wing?"
